Subject: Re: [PATCH] rtc: i2c/spi: Avoid inclusion of REGMAP support when not
needed
Hi Geert,
I love your patch! Yet something to improve:
[auto build test ERROR on abelloni/rtc-next]
[also build test ERROR on v5.5-rc5 next-20200110]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system. BTW, we also suggest to use '--base' option to specify the
base tree in git format-patch, please see https://stackoverflow.com/a/37406982]
